I have no doubt that a better pilot would improve things, but I'm more inclined to hack off the back and make a new piston. My difficulty is however where to find a suitable tube to cast it in, you don't really find syringes bigger than 60mL, so i might just go for a smaller barrel after all.

Ya know jsr, I can pilot the 2 inch piston on my hybrid with a schrader. I know you must have had some traumatic early-childhood experience with large amounts of dead space, but a little extra won't kill you if it means getting the gun to work

Other than that nice job, Maybe if you take the guts out of the schrader you could pilot it by just disconnecting the hose.

JSR- by looking at your diagrams, I dont see how air is getting into the chamber. I hope lack of air isnt the problem, but im just throwing that out there. I probably missed something and will look like a tard posting this but whatever.

Stupid quote of the now:

"only the last two feet hear the end is black cellular core"
"I'm taking it to 300 psi"
